Mossawir Lan Messenger 3 was one of my university time project. I maintained Mossawir Lan Messenger till version 3. unfortunately i am not able to maintain the software becuase of 2 reasons.
currently i have no plan to make version 4 but might be in future. I have got very good response from the people around the globe using Mossawir Lan Messenger 3 in their organization.
Mossawir Lan Messenger 3 is available for download and it is still fully functional. you can use it as it is. you may send me queries via contact form.
