The explanation might then be, Soulcatcher, that since I've just installed fresh Windows and the most recent versions of all browsers, the issue perhaps only appears in the newest versions of those browsers... I'm typing this in Firefox 3.5.3 right now, but the Link and HTML buttons do not work for me in Chrome 3.0.195.21, either. Casique did not specify which browser he's using.
As to Opera, it worked flawlessly on this site before August 13, both for the game & the forum. All of my forum posts submitted before August 13 were written in Opera. Especially for text-based discussion forums, Opera is blazingly fast compared to the distinctly tardier Chrome, Firefox & IE.
Snaike:I hate to go all 'Faterson' on you and all.. but
Ah, you loved every second of it! 
You're correct, Snaike, we've hijacked Casique's thread. What we've been discussing is a worthwhile topic by itself, though. The correct moderating response at this point would be to manually fix the broken link in Casique's opening post, and then split this topic, renaming the second topic Dysfunctional Link & HTML Buttons in Forum Posts, or some such, and transferring it to the Bug Log forum subsection. Of course, we don't have that kind of a moderator here, so the split probably won't happen. 
PS: It's already been discovered why I can't access the Ladders site... My IP address apparently got blocked by an English company by mistake; 
we're in the process of unblocking it right now. Apologies to all League Tables participants; all technical game results and next month's divisions should be posted later tonight.
