Looks like you have HTML code in your signature which is not allowed according to the signature edit page. Try cleaning your signature and make sure it conforms to all of the guidelines and rules.
Signature links are not meant to have the NF attribute, thats the point. Really, so did you actually bother to look? His first link is fine but his second link to the "web hosting" definetely has the NF attribute applied so there is a problem with his signature.
i don't think all sig links are nofollow. i stand to be corrected cause i just checked. i think there may be something wrong with your url structure. check same url for the first link and do same with second to see if you'll have it fixed.
No because signature links of DP are do follow and cheesee have not idea to check dofollow and nofollow links or he is joking, i am sure. Download search status with firefox and check all links instantly that its dofollow or nofollow. Thanks RS Seo Solution
You links should be dofollow. You should take a look at editing your sig. These forums links are good soruces of backlinks, however make sure you do not spam, and add great insight into converstations.
And if it's noffolow what Noffolow means it doesn't pass PR ... PR is important only for idiots and noobs ...
I think that you must have them formatted like that, by default they should be follow unless they have recently changed something here.
