Post installation

I am new to Drupal and am working on creating a website for a non profit organization. The initial site will have 4 main navigation links (top navigation) and within each of these 4 main navigation areas there will be a subnav (left side) that will contain additional links. I have played around with the menu module and see how to create a menu, enable the block, and restrict display to certain areas of the site. However, after reading some posts I am wondering if this is the best way to create the basic menu structure or should I be looking at taxonomy_menu or perhaps something else.

Hi. My customers are having trouble posting or editing content of any kind on their Drupal site. After checking into it and then viewing the error logs on the server I found this:

Hey all,

For reference, I'm porting this health-based site over to drupal:
http://www.chronicbabe.com/

I'm doing pretty good, just getting into templating and it's starting to make sense (PHP Template). But I'm still classifying myself as "newbie" - case in point:

Currently my almost clean drupal 4.7 test site shows an empty admin/modules page. The page is 100% empty, the server only returns a HTTP 200 error and nothing more. When I increase PHP's memory limit to 9M (instead of 8M) is works. PHP doesn't report a memory exhaustion nor is anything logged in the apache logs (not even the request).

Does anyone know how to add stuff like a custom image/images, custom text, etc to the rss feeds which come from various areas of a drupal site?

Thanks in advance!

PS: I did search and came up with nothing useful

OK. I have the above 3 mentioned items in my installation. Perhaps something is messed up, and I need to re-install, but I thought I would ask here first.

I have a similar issue stated here. http://drupal.org/node/52730

Basically, I go into my forum (off the menu) and create a new topic. This topic never shows up in the forum list. Its created, and when i look at the forums, it shows that there are x new topics. However, when i go to the forum, it doesnt show any?

Does this make sense?
