Can't delete comments in forums

Issue Summary

I just insatlled User Comment and it works fine almost everywhere in my site, but in forums (I have installed forum + advanced forum) the comments can be approved but can't be deleted by node authors. I observed that on the approve button there is a link to mysite/usercomment/approve/... but on the delete button the link is mysite/comment/delete/..., so that it seems that the delete button still depends on the comment module instead of the usercomment module. Any idea about how to solve this? Thank you in advance.
