1. Download process
To download proxies from sources launch download threads in the "Control" window:

The source, which is being downloaded at the moment, is marked by the corresponding symbol.
2. Source status
Source statuses change after each download:
Red sources - not available addresses or nonexistent files. Their rating is falling.
Yellow sources - available addresses but with no proxies found.
Possible reasons:
1. The resource has been relocated - now there are no proxies at the current address.
2. Default sets of regular expressions haven't recognized any proxies.
Green sources - sources with proxies found. The rating of these sources is growing.
3. Download intervals
Each source is downloaded in time intervals specified in the settings.
If you need to download a source immediately, select the "Speed up" option in the popup menu.
If new proxies appear on the resource, they will be added into the base.
