In order to set up custom styles in the drop-down list to the CKEditor toolbar is not that difficult but the instructions here is not very well defines when you are integrating with Drupal.

Simply copy the sites/all/modules/ckeditor/ckeditor.styles.js file into your theme directory. 

Setting up one Solr server with two or more Drupal sites takes some additional configuration. If this is not done, all of the data for each site goes into the same index and when searching on one site, results are returned from both sites. If that's not the desired result (faceting won't currently work correctly), then it is necessary to set up a separate Solr core for each site. Each core is a totally independent search index.

New modules to look at:

Contextual Administration

Flex Slider

If you are new to developing for Drupal 7 or upgrading from another version, the examples modules is a GREAT module for examples on how to develop for Drupal using the API. It gives you the basic of a lot of the common things you do when developing. Some examples included are theming (hook_theme), running cron job (hook_cron), forms (hook_form, hook_element_info), menu, node and so much more!!

An intranet "portal" is defined not merely by the technology platform that makes it run. When you get beyond the buzzword, a portal supports an organization and its employees by aggregating and organizing all the
information and applications that users want and need to function effectively in their jobs.

Fuzetto Web Solutions has been success using a Drupal Process based on a session from the Do It With Drupal conference.

I have found that every project I work on that follows this process has been on time, on budget and stress free. We are working on developing on this process that allows our clients to be more in tune with the status.

Fuzetto Web Solutions offers group training and one-on-one mentoring.

We customize our training based on the needs of the individuals that are participating. Training can include site building, site administration, module development, theming and much more.

One-on-one mentoring is individual support for learning Drupal or just helping people getting through troubles they are having.

Please contact us if you are interested in Drupal Training and you will be contacted when the next training session is scheduled.

Have you wasted time trying to figure out why something won't worked and then find out all you needed to do was clear the cache?

UGH!

When in doubt always clear the cache so you can just rule that out.

You might also want to check the logs. You can get clues there.
