I've designed this to be a very lightweight mod. It uses a series of carefully conditioned perks to accomplish nearly all of it's changes. The only script included in the mod is the MCM script that controls the menu options, so the mod will not cause any performance hit or save game bloat, and can be uninstalled cleanly at any time. To uninstall, go to the Mod Configuration Menu and click "Stop Mod." Once the mod is deactivated, simply delete the mod from your data folder.
Adjust barter rates to suit your tastes. Do you want to make it more difficult to accumulate vast amounts of money from selling items? Do you want to decrease the effect that your Speech skill has on prices and lend some extra importance to the Speech perks? However, this is one of the features that can conflict with other mods, so if you don't want Trade & Barter to override the values set by another mod, simply make sure this feature is deselected. By default, it is already deselected.
To try a time bank, search online for one in your local area using TimeBanks.org. How time banks are managed varies according to the region, so it is important (and often mandatory) to attend an initial meeting that explains the general rules of your local chapter. Once you do this, you’re ready to start trading away. Your services and contacts are identified through the local time bank website.
