Thanks Diki,
let's hope there are interested parties. After all, the reason I took the liberty of creating the particular account, is that I thought your idea was something that was worth the time, even if I myself don't have ANY use of this at all.

Rikki,
the gmail account is currently at 6.3GB and counting up. if you log on the account i created using the details above, you will see the counter in the first page, going up as you look at it.
as for the spam, you are right, there is always the danger, but
1) it is free, and beggars can't be choosers.
2) i have that kind of acccount for a while now, (i am careful of not giving this account when i log on to sites that require registration, I have another one for just that) and i havent received a single spam mail. I believe, I hope, that if we all simply use that account just to log on and see what others posted, or to mail TO that account something for them, spam will not be an issue.
3) since supposedly MANY people will access it to see the posts, if each one of us deletes one spam mail, the account will be spam free.

4) and OF COURSE, we can set up anothe account, say "synthzonemembersongs" so anyone wanting to post a song or two, just mails them there and notifies the others here.
