You can insert linebreaks.
I guess it's for the reason of occasional excessive vertical space use. It's easy to drop drunk on your keyboard or hit "Enter" maliciously...
I can see it's common to deal with it by capping the excess.
Search before adding a new post or thread to see if the topic has already been covered.
Those topics violate the forum rules, once there was already https://forums.opera.com/topic/28535/opening-new-tab-with-mouse-it-s-not-select-the-address-bar-automatically-for-typing/16
I could have just locked/deleted the topic but I just merged it to the older one.
Not sure why is the font on your screenshot garbled.
It should look totally different:
That's how it renders on my (and everyone else I've surveyed) computer.
For the record, the fonts we use are (in order of preference: basis_grotesque, Helvetica, Arial, sans-serif but it really does not look like problem is with the font but rather something on your end (especially since you're saying that the same problem on other pages).
Are you on a mobile device? As far as posting goes, if you have a wide enough screen you see a two-pane view with text entry on the left and preview on the right (though you can disable the preview pane), and on the right are a Discard and Submit button. On a narrow screen there's no preview, and above the formatting tools is sort of a title bar - the right-pointing arrow at the right end of the title bar is the Submit button. (I didn't pay attention to it, but I presume there must be a discard button on the left.)
You can also hide the reply field (to view something else, like a message you are replying to) by tapping the orange circle, then come back to it by tapping the circle again.
You see the three dots at the bottom of the post? You click on that and a menu appears with options such as Bookmark, Edit (if you are allowed to edit that post), etc., and Report post to moderator. Alternatively you could send any of the moderators a private message - I've had users ask me to correct typos in their posts by PM.
See your avatar over there in the top right corner? If you click on it you'll see an option "Edit profile" - that covers website, birthday and so on. After you save that, click on the three dots (right side near the top) and choose Settings, and you'll be able to set whether people can see your name, email, and various forum settings.
It appears you have feedzpipe adware that has taken up residence in your Opera browser, either as an extension or auto-loading webpage. You'll have to remove the infecting extension and/or stop the auto-loading webpage. You probably should ask an Opera Forums moderator to move this thread to the Opera For Windows forum, which is a more appropriate place for it (this sub-forum is just for issues involving the forum itself).
About the smilies on the forum.
In the "Activity" section, we have way too many very similar sports pictures, but only a few for music. I'd like to have more, much more for music, even we could split the category into a few: Sports, Music, Business, Leisure. I'd like to see less numbers of similar pictures of different colours but more activities represented.
It seems to happen that the user list displays single member names twice:
While I was afraid at first glance that a unique member name could be assigned more than once during the registration process, I do think now that it is just a representation error in the user list, because both shown member profiles are linked to the same address.
I mention that because I don't know which event could trigger the occurence of that display bug.
I see this message only when the Opera VPN is enabled. In the latter case I get that message presented on all forums using the same forum software as this one does.
Maybe it has something to do with how that forum software is working (and the VPN).
