Welcome Hugo - thanks for the introduction post; we're (mostly) a pretty sociable bunch on here, the G Scale hobby is like that, and we like to get to know people who join up! Even if you're only joining in order to sell the collection you've inherited, you can still get a lot of help and advice from the folks on here. Posting links to your eBay listings is fine, but if you want to stick around a for a little while and chat to us all, then you'll also be able to put things up on the "For Sale" threads (as Pugs says above, there are limits to the amount of items the moderators allow to be listed in that section at any one time, but if you're moving the collection over a period of time then that shouldn't be a problem); just be aware that there ARE some simple rules in the For Sale section, they are all listed there - they are pretty common-sense stuff, intended to help smooth transactions between buyers and sellers - but be aware that it is NOT a substitute for eBay and the like - it's really more like a card in a newsagent's window, purely to make the first introduction - from there on it's all done with (hopefully) trust and honesty on both sides.
I don't think anyone here would have any objection if you just gave us a rough idea of what sort of stuff you have in the collection.... is it mostly Swiss outline (like the two locos you've had up on eBay)? Do you also have rolling stock, track, control systems etc?
Best,
Jon.
