It doesn't matter too much other than I keep getting asked to Buy a license for XenForo instead of getting to the Resource index
Would a more logical order be:
Home > Buy > Forums > Resources > Members?
Would equally have the same problem for a while as it would take some getting used to, but for a couple of reasons:
1) Presumably the ordering issue is because of both Buy and Resources tab being in position "Middle" and there being no display order mechanism. Having it in the "Home" position should keep it where it is.
2) Home and Buy both redirect to the "front page" whereas everything else is part of the forum so grouping them may be logical.
