Hacman has a Telegram group. This contains many Hackspace members, as well as interested or interesting people. It's a good place to ask questions for a quick answer, ask for advice, or share news and links of interest to fellow hackers. There are web clients for Telegram, as well as official clients for Windows, Linux, OS X, Android, iOS, and Windows Phone. You will need a phone number (not necessarily a UK one) to sign up for Telegram.
This is a relatively high traffic channel (replacing our IRC channel, which is no longer very active). It's recommended that if using a phone app you disable notifications for the group (you will still receive notifications if someone sends you a PM, or if someone addresses or mentions you specifically).
Please familiarise yourself with our Code of Conduct before chatting.
