Used stamps exchanges.

I am a beginner in stamp collecting. I only have stamps from USA and Canada to offer for exchange. I say this in my profile. However, my last two exchange partners want stamps I do NOT have. I can not send what I do not have. Not sure what to do. I e-mailed one person and told them.

hello >^.^< you do not need to worry about that, everyone can send whichever country stamps they have -it´s about 100 different stamps in good condition which is required... wishlists and collection preferences in profiles are just extra information if one happens to have a lot to choose from then it´s nice to pay attention to them :)
