This is not a "social media" site as such. If you're planning a litter pick, you can opt for the system to notify members near you, and when a new group is created, again local members will be notified. You can opt out of such notifications at any time. If you create an event you may include your contact details if you wish and they will be shared with recipients of the notification, but that's entirely up to you. Any subsequent communication would be directly between you and the other person, off the LitterPick.UK site.
Additionally, you may message individual members. These messages will show in their inbox on the site, and they'll be notified by a daily email when there are new notifications. To avoid abuse of this system, individual members may send a maximum of 5 messages per day in total. If we receive reports of abuse from other members, admins reserve the right to disable this facility either temporarily or permanently.
Group administrators may send a message to all members of the group, up to a maximum of 3 different messages per day. Again this reduces the risk of spam, whilst allowing group admins give urgent updates (e.g. change of pick meeting point, or cancellation due to weather etc).
The messaging system is only partially implemented in the beta release, with only system-generated messages.
We'll be adding lots more topics here; partly as functionality increases, partly to fill in on what's already here
