er ... when I try to send a pm to GUEST.BaldEagle2's secret santa's elves the system won't let me.

(It's not my fault - I TOLD you I was new at all this).

So how do I let my secret santa know that my preferred t-shirt size is Large without making the fact completely public, and inviting all sorts of ribald comments and derision (particularly from people who's id's rhyme with "Shamos")?

Any advice (particularly from you LtS), would be most useful, I can tell you.

TIA (whatever that may mean, but everyone else seems to say it. A lot.)
