I can't seem to post any comments.

OK, well this is my first forum post and im sure this is the correct section. Anyways, recently, whenever i try to post a comment, it doesn't seem to be posted. I do Ctrl-F to search for my username and i can't find it. I checked the previous mangas/doujins i read and i do see my comments, but now i am incapable of posting comments. I got plenty of witty comments for some of the recent mangas/doinjins that im reading, but i cant post. Help plz! :(

So you can't comment on manga and doujins?
