i guess its a case of this a forum and not a shop front and i'm not entirely sure what it is you're asking
the question in the poll is should you be allowed to refer services not offered by RT; well the answer is you can. but if you're asking to
recommend a service "before" someone asked
then of course you cant. this is a forum, not a market
if someone asks for a service on any of the forums and you pm them there isn't an issue ... you could even put something in your signature; as long as it's not taking the p%^s, re. the services you offer. alternatively if someone asks for a service or help; reply to the post ...
but your poll question and what it is you're actually asking for are two different things
