Hi,
Do you have any plans to do a social network like extension?
Wall is a good product and expanding to do some of the facebooky things could be very helpful.
I've looked at jomsocial and others but they all are very pricy for a project I have that will not generate any money, so self funding.
I don't mind paying for things but they never provide a year of updates without a large cash investment and I can't stretch that far to need to update due to j4 changes....
