Links in forums picked up by search engines?

First off, sorry if this is the wrong forum but I couldn't find anywhere to put this... I'm just curious, if I post a link to a site in a thread here will it get picked up by search engines? I want some design feedback on a site but my client does not want it picked up by any search engines at the moment.

Thanks in advance,

Yes, it will. Don't post it if they don't want it indexed.
