After several hours of fighting the server, tripedia.org is online again. Most improvements are "under the hood", so you won't recognize much change.
However, there's an all-new process of finding and selecting cities for your destinations: Now you can instantly see which cities you may select, while still typing the name! It's also possible to find cities by coordinates (i.e. you can click anywhere on the map and find cities nearby), and to fine-adjust destination positions by dragging the corresponding marker on the map.
Please let me know if you like it, resp. if there are any problems (which is quite likely)!
