Don’t know if I’m missing something but how do you contact someone in the Used Instruments Exchange also how do you list something?
If I’m being really stupid here accept my apologies in advance 
You contact them through the PM (private message function within the C&F board) or the Email buttons at the bottom of the seller’s post in the UIE. If they have provided another means of communication within their post, use that. If they have also posted a copy or link to their UIE in the appropriate forum (such as Flute, Whistle, Pipes), you are allowed to reply in that thread (just not in the UIE thread), although your post would then be public.
The UIE Forum Rules are here: https://forums.chiffandfipple.com/t/forum-rules/72835/1
Policies affecting New User Registrations, which might have initially affected your ability to submit UIE posts (minimum C&F board postings requirements), are here: https://forums.chiffandfipple.com/t/important-policy-change-new-user-registrations/89140/1
To list something in the UIE (for instance, a FS: [For Sale] post), just enter that board, and use the “New Topic” button to start a new thread, title it properly (FS: = For Sale, WTB: = Wanted to Buy, eBay if listing an auction), and write a description in the post, and perhaps a price. If you have pictures, videos or sound samples, include them, or add them in a Reply message, or give a link to where they can be found. There is a Guide to Posting Images ( https://forums.chiffandfipple.com/t/guide-to-posting-images/22873/1 ) found in the Forum Support board, and there is also a Test Forum board in which to practice.
Thanks but I seem to lack both the PM and New Topic button, may be something in the New User link you sent me.
Thanks for that.
Looks like you’re all set, now.
