Sure, I've done so from the very start.

See here I kind of disagree, Even with 2000 images per year, you will spent
12.5 year to get to 25000 images, by the computers will be able to read a
billion image database (in its current XML format) in a fraction of a second.
But as I said before, lets see, if a huge amount of users get databases which
are this size, I will reconsider.

| more than one person to work against a single image-archive. This is a

I agree with the multi user issue, but on that issue my point is very clear -
I'm not going to spent a single minute of my spare time on developing
features in kimdaba that only professionals gain something from. If a picture
company (or whatever such places are called) are going to save a lot of time
from kimdaba, they should find their wallet fast, and I'll tell them my
account number ;-)
Seriously, I hope that such people will see the quality in KimDaBa, and start
sponsoring features that are of special interest to them.
