Ok i tested the forum section of 1.8version to see if 1.7 bugs were fixed or not....but i guess bugs still exists in 1.8 version
1st Bug) "Quote" Button is still moving in I.E 7 and other previous version of mozilla and chrome... (still 40-50% of people use I.E 7 due to bugs in I.E 8), here's the screenshot - http://a.imageshack.us/img833/6683/forumbug.jpg
2nd Bug) If username is long the forum left column doesn't wrap the username and other data and the long data/text goes out of the table width. here's the screenshot - http://a.imageshack.us/img833/6683/forumbug.jpg
3rd Bug) Quote Button functionality doesn't work if [CODE.] tag has been used, but that's ok as this bug is scheduled to be fixed in 1.9, screenshot - http://a.imageshack.us/img833/6683/forumbug.jpg
