The notifications system has been great from the beginning, but a couple small things have been bugging me for a while. Here are some suggestions for improvement.
1. Dispatch authors get a notification when someone pins their dispatch. The notification should include the pinning nation, a link to the dispatch, and the region. ("Helaw pinned your dispatch in Conch Kingdom.")
2. All ROs with Embassies authority get a notification when another region requests embassies with their own. At present, only the founder and delegate get this notification, but regions often have Diplomacy Officers (or a similar position) in charge of handling embassies.
3. Nations receive a notification when they are edited into a dispatch, not just when they are mentioned in the original text. They would only be notified once ever for that particular dispatch.
4. This one is more of a minor fix than a suggestion. On the Subscriptions page, the checkboxes are fuzzy and low-res. Other checkboxes on the site are much crisper in comparison. In the below screenshot, the first three boxes are from the TG Settings page, and the last three are from the Subscriptions page. Obligatory: running Firefox 52 on Windows 10.
