Warm Welcome to you Elfie!
There is no 'warm-up' or 'cool-off' convetion here; straightaway you can start posting and also take part in discussion.
On the attachment-question, I really don't know your problem. As far I know, only links, which take you to the designated sites/programs, are provided. Anyway I leave that questions to be answered by my senior AR mates for you.
Looking forward for your active participation in AR,
