Personally I choose to send a polite e-mail. If no e-mail addy is available then I will politely IM the vender. I choose this after reading about one poor vender who was so overwhelmed with IMs that they left Rendo because "I can't even get to the forums through all the IMs". Then you have to be patiant as a vendor who is popular will surley have a LARGE InBox as well. Persistance is my weapon, but careful not to over-do it, then it becomes nusance and that too is negative in my favor. I haven't really had a bad experiance here nor else where with venders. Several little things I just put an effort forth and fix myself, anything I can't I just ask - politely, as if I where another sending a request to myself..
