Very possible that you need to register first... since Juni, forum security have increased a little... was tired of cleaning spam post/topic and spam account... around 2000 new account by month where 95% are used for spam...
Once you are there, PM me ( i am called Fileosoft there ) and i can give you a mod dev status...
If you need some help about modeling/segmenting/UV optimization/basic texturing, don't hesitate to contact me... i am not a top expert but have some experience... by example, for these mod, i have made the UNSC phoenix, the UNSC supercarrier and the cov assault carrier along some other minor work requested by Canadaman ( mainly UV work )... and the only way to give some value to experience is sharing it...
Almost forget, the mod dev status is universal for all mod hosted on danmangame... it mean that you are not limited to model for the Halo mod... you have access to all the dev section of all mod... one of the usefull modeler there, who work on numerous mod is called Kobalt and he is very helpful for newbies too...
