Every week ENTS members congregate at the space to socialize and work on their projects. This is an open format evening where it's just as likely to spend the whole night in the lounge chatting as it is to be toiling away at a project.
There are no formal times for HackTuesday, however it's safe to expect members to be around from 6pm until 10pm.
HackTuesday is also a great way to introduce new people to ENTS as they're able to tour the space and meet part of the membership. It's also very easy for people to come and go without disturbing other members, unlike at the monthly meetings.
