Yes you will but it's not what donating is about, full access is a side effect of donating, I have full access but still continue to donate yearly.
If you make just 20 reasonable posts then you will still get full access so it's not about the donation.
To make 20 reasonable posts is easy if you look around the forums there is so much more than just cable stuff.
DW is a community so the more we put in the more we get out, how it is supposed to work is you join get access by posting then decide yes I like the community and then donate to help with the server costs.
Donating for access works but it's not what the donation system is for.
