I dont know about other countries -- but here in australia mainly sydney and melbourne not sure about the other states --- a couple of the larger masjids have a OPEN DAY annually -- where they advertise it heavily in the community for locals to come and have a guided tour of the masjid, meet brothers and sisters, ask questions get to know muslims and islam in a fun friendly environment and staying true to the Aussie way of life --- they have a big barbie (halal of course)

I know when i was thinking of reverting i just missed an open day and it was disappointing cause i didnt know any sisters and thats the only time i thought i woulda been strong enough to waltz into a masjid on my own lol and its a great way for those who want to revert a chance to meet new muslim friends etc.

And of course you must let members of our own muslim community know too as they need to be a bit more relaxed with the broader community who may not know the dress rules.

I personally think they should do one of these every month or every couple of months -- one a year is just not enough.
