I recently came across a question which was self-answered by the author after consulting with an individual outside of StackExchange. This seems alright, and the author included enough information in his answer to be useful to future readers.
However, what I questioned was the use of an eLance link to give credit to the individual who helped the author. Previous meta discussions seemed to establish that the inclusion of eLance links for paid support to answer questions were inappropriate, however, none touched on using it to credit outside help.
I took the previous discussions as precedence and I flagged the answer. However, after reading a moderator's flag note I edited out the eLance link; switching instead to a LinkedIn profile1 so as to not lose the intent of attribution.
When receiving outside help--perhaps in parallel to help on SE--is it appropriate to provide links to eLance profiles of the individuals who "solved" your problem?
1. I'm not sure if this was the best approach, but it seemed akin to a link to a blog.
