The shop is available on Galatic Science but I do not know how to convert tokens into credits. I feel like a fool, because I did it already, but at my age sometimes I just cant remember what I did. Please just give me a conversion rate and I might be able to get what I need in about a week or so. Thanks.
You cannot convert tokens to credits. Credits can only be obtained by leaving a review for the server. They previously were a purchased currency, but Mojang felt this violated their EULA so it is no longer possible. Tokens can become MyMs and Claimblocks both restricted to the server they are converted on. /shop Then click the emerald to the appropriate currency, in this case tokens to MyMs to buy the RF Tools crystals as there isn't really anything else purchasable on that server.
