About SeneJUG Town

Welcome to SeneJUG Town, our community on the web. Here you will find a place to meet and socialize with your fellow JUG members. This community is a step beyond static HTML and mailing lists. Explore the features and you will find a rich environment that allows you to communicate far and leave a written record that will help the community well into the future.

SeneJUG Town is here for you. To begin with, you can customize your homepage. Each member has a blog. When you post a blog, it is also displayed on the Codetown homepage! You can create Discussions, add Comments, upload multimedia, join other Groups and use the powerful Invite feature to ask your friends and colleagues to join.

Since we're the West African JUG, a large group geographically, there are many distant members you can stay in touch with through this Group. Look for members in France and Morocco, too!

We look forward to seeing the miles between us grow smaller, virtually. All the best!

Lamine Ba and Michael Levin
Co-Chairmen, The West African JUG
