To contact the Gluon team, there are several options:

#Gluon on Freenode

The primary course of interaction between the team members is the IRC channel, which you can connect to simply by clicking on the above link (if you have an IRC client set up to accept the link), or by connecting to the chat.freenode.net server, port 6667, and entering the channel #gluon

The Mailing List

The secondary point of contact for the team is the mailing list, which you subscribe to by sending an email to gluon-request@kde.org with the subject "subscribe". If you wish to see what has already been sent there, the archives can be found at https://mail.kde.org/mailman/listinfo/gluon

The Forum

Finally, we have a forum, hosted graciously by the KDE Forums, which is frequented by many KDE enthusiasts and soon, we hope, by Gluon enthusiasts who may be encountering KDE for the first time.

Microblog Identi.ca

You can follow us by subscribing to our group over on Identi.ca. If you're not on Identi.ca, most of the posts, there are forwarded to twitter on hashtag gluon as well.

Facebook

Gluon's Facebook page.

Reporting Bugs

Should you wish to report any bugs, please use the KDE bug tracker to report bugs to us. To do so, open up any KDE program, click Help and Report Bug... and select the Gluon application in the drop-down list. When you click Launch Bug Report Wizard you will be taken to the appropriate page for reporting bugs.

If you do not wish to do this for whatever reason, or lack the possibility of doing so, please go directly to our Bug Tracker and report the bugs through there. This is, in fact, the same site as the above method provides, but the dialogue will take you past the initial steps of providing information about version and software package.
