Forums profiles are good, if you have made them with good sens - means if you are using proxies and getting links from high PR forums, it will help your ranking when they will be indexed and crawled. Use Pinging + Rss submission for your profiles links to get more advantages and ranking improvements. ( I did forums profile from same ip with sick submitter but did not get the results that i was looking for, may i missed the guide line. )
One more thing, you can do a Scrape Box blast for your high PR forums profiles to get them index and more value, i see this technique on my one competitor website and liked it.
I am willing to buy idreesfarooq service for forums profile as he is using and offering very interesting wheel and i have read very good reviews from many Experts here. You may also give him a try like me and estimate the results.
