Hello all.

I'm just joining the list. I've browsed through the archives but I have a couple of questions.

I just installed the 1.4 beta. We like the Elastic skin so we are planning to use it as a default for all my users.. I plan to keep it updated, but I have a couple of questions.

1. Is it possible to have a popup or a modal when a user first signs in -- Just a simple window with the TOS for the account with an OK, or Accept button, that lets you go on to the second window which lets you complete your Identity. 
2. I noticed there are user levels. 1 - 4. 4 being default. how would I go about managing those on a per user, or per group basis? I want MOST users not to be able to modify their email address or their organization.
3. Using the elastic skin -- I noticed on the configs that I can put a logo on the main screen, in fact I was able to put a logo but it is stretched in an ugly way. What are the proper dimensions for my logo? Can I specify a different logo on the main mail page? I see the logo on the upper left corner of my screen, but it's just a part of the logo. I would like to specify a different one there. I have 3 specified on my array by looking at examples: one for '*' which points to a large logo, one for ':favicon', and one for ':small', but the :small one does not show on the upper left. it's part of the '*' one.
4. Is there a way to resize the center pane (or hide/minimize it) when needed? (for example, when an extraordinarily wide message, so that I don't have to scroll side to side too much) -- This would also need to be possible when redacting mail so that the Options and Attachments column does not get in the way. 

That is all for now. I am sure I will have more questions as I keep using the system.

Thank you all for your help.
