People sometimes have trouble figuring out how to add a row to a table, such as in the Tribe Contacts page.
If you're using the "classic editor", it's easy. Right click on a cell in the table. This will bring up a dialogue box with options including "Cell", "Row", and "Column". Select "Row", and you'll see options including "Insert Row Before" and "Insert Row After". Choose one of those.
If you're using the newer "Visual Editor" it is somewhat more difficult and much less obvious.
1. Left-click on any of the cells in the table other than the column headers. This should select the cell, highlighting it in light blue. It should also light thin light-blue rectangles at the top of that column and at the right of that row.
2. Left-click on the light-blue rectangle at the right. This should bring up a box with three options.
3. The top symbol is to add a new row above the current row; the middle symbol is to add a new row below the current row. The bottom symbol is for deleting the current row. Click on one of the first two.
