Module development and code questions

I'd like a similar feature for a site I am planning. Basically a user profile where the user can write a longer presentation, upload and add personal photos and images, use different fonts and colors and more or less customize it and make it personal.

My idea has been to use the guestbook module for personal guestbooks and modify the gallery module to allow users to create personal galleries with photos other users can comment on.

Is it possible to call two different databases within a module?

I am wanting to use the database for my module and another database from a different module.

Any ideas?

Hi,

Hi
I have a problem in using flexinode module. I used drupal 4.6.3.My user account can edit some data(node) that already entered but some(node) cannot edit. When i check in Mysql database, there is no difference between edited data and not edited data. When i check the flexinode module i found it controls with user_access function. But i could not find that function in detail. I searched in the whole drupal and i could not find where that function wrote. Where should i find it? Please help me. Thanks in advance.

I'm not really sure where to post this so I've put it here; if this is not the proper place for a request like this then I apologize.

I currently am using code I found and slightly modified in a node history block. The block shows the last modified node, who it is by, and at what time they modified it. I've included the code with my alterations at the bottom of this post.

This code works great for a block as the formatting is perfectly suitable. What I am looking to do with it, though, is make a page out of it that's dedicated to showing the history of a specific type of node (in my case, book). The formatting is not very suitable for this purpose. See the formatting examples below.

Is there some type of friends module already available for adding and managing other users from the site as friends... pretty much like how myspace does it.

Does anybody know if something like this already exists?

Thanks!
