If you only take one thing from this review - use Gumtree instead.
Musicians-in-your-city has a huge amount of baffling rules. Maybe part of their autocratic approach is due being lost in translation from their native german, but it's a rough user experience.
Say you're looking for a drummer - you have to fill in the comments field with 'something meaningful and interesting - min 50 characters' but you're not allowed to say 'what you are looking for' nor 'anything about your band'.
All quite odd, and there's no help at all in completing.
If they deem your entry against their rules - your account is frozen for 12 hours, whilst 'contacting support is forbidden during this time'.
You then make the amend, and have to wait another 12 hours for them to approve, again 'contacting support is forbidden.'
Totally bizarre they feel the need to run the site in this way. Much nicer would be to tell people they've got it wrong, give them guidance on what is needed to change and a chance to change it before freezing them out.
It probably explains why so few people are on this site, and why engaging with them is so stilted and difficult.
Nice idea, appalling execution and waste of money.
