Thanks alot si Zakaria for your remark. As per finding a solution to that problem I am telling you now that it s somehow impossible just for time being and that due to some hindrances; first of which is the free sub-domain we are using. You can see that it is melta.forumactif.com and not www.melta.com. In order to be able to get a free domain, you should have 1500 points or more. That can be reached either via ALLOPASS (phone service) or PAYBALL. Getting a free domain offers you a considerable space where you can host your files in the forum's server; thus enabling members to get a direct download link instead of going dizzy over external web hosting services like rapidshare, zshare or mihd.
One thing that I would like to add is that if you happen to check some forums like startimes2 or projectw you cannot fail to notice that they are not offering the service you are asking for. They have their own domain not like us, but that does not mean that members got the right to upload files to their forum.

I am doing my best dear colleague, and I will announce a service soon in the forum for members willing to support the forum financially.

Till then, do please accept my apologies all.
Thanks once again for your remark.
