I just visited your website. So, I didn't find it that convenient after visiting. To say the least, I noticed a lot of bugs, that feel uncomfortable while reading. First of all, it takes a long time to load, then the quotes are not clear. Moreover you cannot visit someone's profile while reading post. These proxies are not very useful tough.
Same. I don't even use any userscript (except Ninja's script to copy signature codes), just raw version, have never felt 'real need' for anything else.
A new patch has been added to the forum, so now you can copy whole code or signature code without any scripts.
PowerGlove sent me a different way of doing this, which is live now, but it's sort of hidden: if you click the blue "Code:" text immediately before the actual code block, then it'll select the whole code block.
