He's trying to suggest to put the WG's username on the subject heading, rather than a "anyone seen her?". Read this.
Ah! Ok. Thanks for the noob-friendly reply! At least i can also follow these rules as and when!

However.... the post was opened in order to reply, so why not include a note similar to yours, seeing as he's in anyway?!
Personally..... I know what is to be incvluded in the thread entitled "have you seen this girl".....
and also "have you seen MaryWebb3829348?"
Either way... if i HAVE seen the girl (named or not), i can input...
and if i HAVEN't seen her, then i either a) just leave the conversation if i'm not interested in the posted profile link.... or b) add YET another potential to my hotlist!
Just my tuppence worth... not having a go or condemning anyone, i just feel a forum is for like minded individuals to banter about stuff!
