From the style of your posts I think you are looking for a far more formalized and structured environment that you are likely to find in most of the GoI community. I also think you are unclear as to the nature of the negotiation taking place.
GoI does have a few clans that try to organize regular practices (skrims) and play in competitive events and it has some that are on things like TS/mumble, but the community is small and tight-knit and most clans don't have the members to do the former. They often also don't need the latter as many treat GoI like a chat client with party chat, or use Steam chat. They don't really need TS. I doubt you want TS specifically so I invite you to look at the deeper reasons for this requirement. I suspect what you are looking for is a communicative and / or social clan. I'd identify clans that meet that requirement, rather than your current approach.
The clans that are active and emphasize communication, even if they are actively recruiting, are looking to see what you can bring to them before they admit you. Taking on a new clan member introduces instability into a social scene and someone inexperienced like yourself can place a burden on that clans educators; many clans have criterion you need to clear. While the clans are competing for new talent, they have limited resources and will want to see some evidence that you are bringing something they want to the table. You are very inexperienced and your interest profile is also one of the more common ones (broadly speaking the community has a shortage of main engineers, a shortage of pilots and a glut of gungineers and gunners). If you really want to find a clan that meets your core desires here you aren't really in a position to ask the clans (especially old, established ones like the Ducks) if they have what it takes, openly ask if the clans treat their members 'like cattle', or reject others out of hand because of specific software requirements. You may have to compromise, and recognize that your hand is weak and the clans who have what you want are holding most of the cards.
