I have edited my club's members list and all I did was remove the placeholder IMG tags for the old extended, special smilies (which no longer work or showed, save for saying "speccool.gif" etc in place of the smiley). Many of these were used and handed out by myself and Mega Man to club members who had extensive collections, posted interesting things and so on (especially as a form of commenting on very rare game consoles in a collection).
So, all I really did was remove 10+ broken IMG tags. Now in my browser (Firefox), the club logo image at the top is HUGE in the thread, and before editing it was much smaller (roughly 350x500 or something). Additionally, the code block in code tags for the signature code to copy into club member's signatures is not showing and making a proper code tag box. Edit: it was working normally before I first edited it, and when I did and submitted it the normal code box went away, and instead it is simply showing as a link (e.g. the end result, as if someone sigged it). I can probably wrap it in code tags again to fix it (I hope?)
Really have no idea what I did or even how to fix it and make that club logo image (that says 'ocn retro') small again. I even tried moving text above it, as well as editing the img tag which appears to have a size definition, obviously making it smaller (it was 500x1000).
Apologies if a bug like this was already posted and if it is known.
