Doing several WordPress installations and adding the plugins you need, one by one, can be a time consuming task. If you do this same process every week, here is a new service to help you out.
Tim Trice, a web developer from Houston, Texas, has put together a Free Custom WordPress Package builder service on his blog. This service bundles up an installation file based on the selection of themes and plugins you want for your WordPress setup.
Simply visit the site and fill in your name and email at the top of the page. Next, select the plugins and themes from the list that you are intending to use, and hit Submit. The custom package download URL will be emailed to you.
The selections available currently are limited, though he is planning to expand it. Check out the service at the link below.
