I think the WYSIWYG editor on the forum should be restricted down. It gives too many HTML options, creating glitches allover the website.
Also in trips I have seen a lot of broken <div> </div> when people quote other people on trips. Also truncated HTML code breaking the whole thing when an IMG is inserted (unable to then access the EDIT button due to broken HTML tags conflicting with the rest of the page).. and also when someone quotes another person, and then edits the comments.. it ends up spitting out the HTML code printed and again.. breaks the conversation.
I think these annoyances should be addressed.. not to mention with a bit of tinkering with a well crafted comment.. can post a security glitch to end users instead of just an annoyance.. since comment HTML code is getting jumbled up with the HTML code of the actual page.
I think this should be limited to using BBCODE (like vBulletin forums use) to insert images etc.. instead of directly allowing users to insert HTML code onto the page.. which is clearly breaking everything.
Not sure if you are using a custom CMS or an off the shelf CMS using what looks like ASP.Net - but these things should be addressed.
