Installing Drupal

I just installed drupal and I'm having problems getting the blogger api to work. I get errors trying to blog with any remote clients (namely w.bloggar and blogbuddy), it usually says something like "only one top level element allowed", or blogbuddy gives me "error 11004: socket" or something like that.

Also, when I try to load my xmlrpc.php file in a web browser, it gives me a fatal error:
Cannot instantiate non-existent class: xmlrpcresp in /home/virtual/site12/fst/var/www/html/includes/xmlrpcs.inc on line 237

I have an ISP now which supports Cron jobs. I have an interface where I can add files to be run by the Cron job.
Which file should I add?
In the documentation it is said that I should add the cron.php on www.drupal.org.
Is that correct?
Shouldn't it rather be the cron.php in the root of my own site?

As You can see I do not really understand this.

Hi All,
I run a local nonprofit community website... www.Goenkar.com. It is currently mostly static html with a few PHP scripts running including phpbb. There are a few problems, the main being the complexity of updatign data and the next being the case of needing to signup separately to use each of teh installed scripts.

So I'm gonna shift the whole site to a CMS and after reviweing about 12 different cms softwares my heart is set on drupal caz it seems to have most of what I need.

There is another complexity in shifting to a cms.
1) The search engines (other than google) do not spider dynamic content. So my search engine ranking would go down eventually.
2) There are a lot of mini sites on the website. Goa is a small state but has plenty of villages. So I will be assigning subdomains for each village. I need this content monitored by pre-designated people from those villages. I need to have a sub-portal kind of system as well as have the headlines, posts, etc. show up on the parent website homepage.
Each sub-portal will have their own theme. Each sub-portal could also have sub-sub-portals and they too with their own theme and layout.

I am on a LAMP, virtual host, 250MB, 1 database, unlimited sub-domains and no root/telnet/ssh access.
The main things needed are the sub-portal functionality and assigning administrators for every sub-portal.

I am pretty good at PHP but your advice on a path to achive the above using drupal would be appreciated. This would save me a lot of time writing my own cms from scratch.

i get this error:

warning: Bad arguments to implode() in c:inetpubwwwrootincludestheme.inc on line 35.

I'd say the link_secondary variable is empty, but where is it defined? How do I add links to this?

I notice that there seems to be more than one version of the CVS files, i.e. what's listed in the CVS repository and what's listed in the downloads section. Am I correct in figuring that the downloads section is different from the repository?
