Module development and code questions

I use(d) the project module for a few php projects and would like to use it for my theme/engine (based on chameleon) that i've been working on. I haven't checked in a while but kind of assumed that it would be ready for 4.5 by now. How is it going? Is the CVS working in 4.5? I tried 4.4 when I upgraded to 4.5 but there were some errors.

This one has me confused.
I am running a single set of code for 3 sites. All have been running for some time.
I was doing some developement on a user profile search module for one of the sites (just simple tweaking as it has been running for some time on a live site) and did encounter a snytax error. Fixed it and the site is fine. This module also runs on the other two sites mentioned.

regardings the chatbox.module, there is only one chat room available. it there possible to customize chat rooms, just like IRC-like features?

I think this would be really cool, and I don't know how to write it myself. It is almost like the "Most recent comments" block, instead I would like to have a "Most recently added image" block (or something along those lines) where the block shows the thumbnail of the newest image and links to it's node. If there is one already, please tell me; if you can help me to make one please tell me also. Thanks.

Hey I'm modifying the Upcoming Events block so that it only shows content from a select Taxonomy.

This is the original code
$result = db_query_range("SELECT n.nid, n.title, n.status, n.moderate, e.* FROM {node} n ". node_access_join_sql() ." INNER JOIN {event} e ON n.nid = e.nid WHERE n.type='event' AND ". node_access_where_sql() ." AND n.status = 1 AND e.start >= $time ORDER BY e.start",0,$limit);

I tried modifying by adding another JOIN to query the taxonomy table, but there is a flaw in my MYSQL.

I have seen my question asked numerous times in the forums, one way or the other, but never answered. Is there any way to remove the 'recent posts' link from the site navigation menu? Yes, you can disable the link in 4.5 and have it disappear, but when you type the URL 'yoursite/tracker', tracker is still accessible. I want the functionality of tracking individual posts on user to user basis withut being overwhelmed by every post available on a site. On active sites, such a link is simply useless--information overload. Also, I prefer Tracker to Workspace. Any suggestions?
