Using forum options on website (RSS??)

[Vixion]

http://www.vbulletin.com/forum/showthread.php?t=113699

I tweaked the external.php file, with an addition that external.php can also read .php files, zo external.php?type=php

And I am using MagpieRSS, to display the external.php?type=rss2 on my website, but I ran into this problem;

(1) I cannot change the maximum amount of characters displayed
(1a) If this can be done, without MagpieRSS, please let me know

Besides that, I am still searching for a way to include the following things into my website;

(1) The number of users online. (See attachment 1)
(2) The name of the newest user. (See attachment 2)
(3) Today's Event

Also, I wanted to know if it's possible, to let people sign-up as a member of the forums, without visiting the forum, so *I think* I need to include the signup-files into my website, in some way. Can this be done?

Please help me out.
