how do i get hold of the session variables data of a particular user provided i have the session id. i suppose this is how u show whos online ...

is it possible to sort a recordset using two fields which r of the same type from 2 diff.tables. say i've 2 tables 'Problem' & 'Reply'. one for real problems details and another with replies to it.
now if i see a problem which is replied to i want to sort the table based on the time of this particular reply as well when i normally sort it based on the 'Problems' time field

i think im trying to mean how different msgs are sorted here in the forum when someone replies to an old posting.


also what kind of security options are advisable for my user/pass system once i put it up online .. i dont know much abt security stuff .. but am willing to look thru ...

ideas please ....
