+----------------------------
+
+A domain transfered to the server can have one of the following status:

[Wladimir Palant, 2012/10/09 11:51:14]

"Status" doesn't seem to be the right word, should be plural anyway - "states"?

[Thomas Greiner, 2012/10/09 13:47:02]

I tried to avoid calling them "types" due to possible problems with reserved
keywords.

+
+* 1: the domain was entered

[Wladimir Palant, 2012/10/09 11:51:14]

Better: "was entered without any further action" - all these domains have been
entered.

+* 2: there was a typo

[Wladimir Palant, 2012/10/09 11:51:14]

Where and what does it have to do with the domain? Better: "the domain was
recognized as a typo"

+* 3: the domain has been corrected

[Wladimir Palant, 2012/10/09 11:51:14]

No, this domain *is* the correction. Meaning: "the domain is a correction that
the user accepted"

+* 4: false positive (domain was corrected even though the typed domain was no typo)

[Wladimir Palant, 2012/10/09 11:51:14]

Better explanation: "user declined our correction"

+
+The server expects the list to be transfered as a JSON object in no particular order. Here is an example:
+
+```js
+{
+  "urlfixer.org": 1,
+  "adblockplus,org": 2,
+  "adblockplus.org": 3,
+  "goggle.com": 1,
+  "google.com": 4
+}
+```
