When you add a note, you should generally only add it on one page.
For example if you want to explain what a pennon (type of flag) is in Dutch, it would be tempting to add it to all the pages which talk about that object, e.g.:
- pennon (type of flag)
- a pennon
- the pennon
- orange pennon
- He added a pennon to his flagpole.
However, it is better to add the explanatory information only on one page, usually on the page specifically about the item. In this instance, the information belongs on the pennon (type of flag) page, because this is the page which all the other phrases include. For example, since the pennon as a page already includes a link to the pennon (type of flag) page, then if the student wants to find out what a pennon is, all they have to do is click on the word pennon in the literal breakdown.
There are a number of reasons why it is better to only write the information in one place.
The main one is that you don't want to have to maintain many pages with the same information; if the information is only in one place, then when you update it (e.g. improve the wording, or add extra information, of make the URL link more user-friendly) then the work is done, and you don't have to change it in several places. In addition, if it is in multiple places, and any changes have to be made in multiple places, then it becomes very difficult to maintain consistency between the pages.
Another reason is to try and keep Lingopolo as clear from Notes as possible. Occassionaly notes are necessary and helpful, but the aim is, as far as possible, to keep explanatory Notes as few as possible.
